`l MPRAOVEMENT IN SASH-FASTENERS.

Specication forming part of Letters Patent No.l 196,630, dated October 30, 1877; application filed i y June27,1877.

"To all 'whom it may conce-m: y

Bei known thatl, FREDERICK GASPAR, of

` Plaineld, in the eountyof Union and State of New Jersey, have invented an Improvement in Sash-Supporters for Gar-Windows,l&c., of

' which the vfollowing is aspeciiication;

. I make use of a toothed rake,`into which a pinion is geared, the two running together as `the sash is moved up and/down, andthere is sliding bolt operated by a bent lever and or to be held in any-position-at which itin ay be placed, alll ashereinafter more fully described and claimed. V

' In the drawing, Figure lis an elevation of i v.a portion of the sash, with the sash-supporter in section; and Fig. 2 is a sectional plan at The sash a and frame b are of any usual i character, and c is the toothed rack recessed into` the window-frame. The plate c is .attached to the Vlower rail of the sash, and at the back of the plate is the pinion h, upon a i stud or gudgeon onthe plate e, said pinion having teeth that gear into the teeth of `the rack c. .4

` i The sliding bolt or latch k is made with an i end adapted to pass in between the teeth of 1 the pinion and. hold the same'rmly, andfthis i bolt k is sustained in loops at theback of the plate c. g

The bent or belllcranklever Z'has its fulc rum at 1', and one end passes into a slot in the bolt k, and the other end is connected by a pin and slot with the vertical sliding thumbpiece n, that passes through a mortise in the plate e, and this thumb-piece, by its weight,

serves to project the latch into the teeth oi' 'the pinion; but a spring, s, may be added,

to render the movement of the latch more rapid.v There may be a stationary stud or linger-piece' above the thumb-piece fn, so that the `two may be grasped inl ng the piece n; andit will be apparent that when this piece n is raised up the bolt will be withdrawn from the pinion, so that the sash is free to be raised Y and pinion h, of the sliding bolt lc, bent lever l, working upon the fulcrum z', and vertical sliding thumb-piece n, substantially as set forth.
